oCIS with WOPI server

Overview

  • oCIS, Wopi server and Collabora running behind Traefik as reverse proxy
  • Collabora enables you to edit text documents in your browser
  • Wopi server acts as a bridge to make the oCIS storage accessible to Collabora
  • Traefik generating self signed certificates for local setup or obtaining valid SSL certificates for a server setup

Find this example on GitHub

The docker stack consists 5 containers. One of them is Traefik, a proxy which is terminating SSL and forwards the requests to oCIS in the internal docker network.

The next container is oCIS itself in a configuration like the oCIS with Traefik example, except that for this example a custom proxy and web UI configuration is used to enable the oCIS Wopi extension.

The oCIS WOPI server extension is running in another container and enables you to open files in Collabora from within ownCloud Web.

The last two containers are the WOPI server and Collabora.

Server Deployment

Requirements

  • Linux server with docker and docker-compose installed
  • Three domains set up and pointing to your server
    • ocis.* for serving oCIS
    • collabora.* for serving Collabora
    • wopiserver.* for serving the WOPI server
    • traefik.* for serving the Traefik dashboard

See also example server setup

Install oCIS and Traefik

  • Clone oCIS repository

    git clone https://github.com/owncloud/ocis.git

  • Go to the deployment example

    cd ocis/deployments/examples/ocis_wopi

  • Open the .env file in a text editor The file by default looks like this:

      # If you're on a internet facing server please comment out following line.
      # It skips certificate validation for various parts of oCIS and is needed if you use self signed certificates.
      INSECURE=true
    
      ### Traefik settings ###
      # Serve Treafik dashboard. Defaults to "false".
      TRAEFIK_DASHBOARD=
      # Domain of Traefik, where you can find the dashboard. Defaults to "traefik.owncloud.test"
      TRAEFIK_DOMAIN=
      # Basic authentication for the dashboard. Defaults to user "admin" and password "admin"
      TRAEFIK_BASIC_AUTH_USERS=
      # Email address for obtaining LetsEncrypt certificates, needs only be changed if this is a public facing server
      TRAEFIK_ACME_MAIL=
    
      ### oCIS settings ###
      # oCIS version. Defaults to "latest"
      OCIS_DOCKER_TAG=
      # Domain of oCIS, where you can find the frontend. Defaults to "ocis.owncloud.test"
      OCIS_DOMAIN=
      # IDP LDAP bind password. Must be changed in order to have a secure oCIS. Defaults to "idp".
      IDP_LDAP_BIND_PASSWORD=
      # Storage LDAP bind password. Must be changed in order to have a secure oCIS. Defaults to "reva".
      STORAGE_LDAP_BIND_PASSWORD=
      # JWT secret which is used for the storage provider. Must be changed in order to have a secure oCIS. Defaults to "Pive-Fumkiu4"
      OCIS_JWT_SECRET=
    
      ### Wopi server settings ###
      # oCIS Wopi server version. Defaults to "latest"
      OCIS_WOPISERVER_DOCKER_TAG=custom
      # cs3org wopi server version. Defaults to "latest"
      CS3ORG_WOPISERVER_DOCKER_TAG=
      # cs3org wopi server domain. Defaults to "wopiserver.owncloud.test"
      WOPISERVER_DOMAIN=
      # JWT secret which is used for the documents to be request by the Wopi client from the cs3org Wopi server. Must be change in order to have a secure Wopi server. Defaults to "Pive-Fumkiu4"
      WOPI_JWT_SECRET=
    
      ### Collabora settings ###
      # Domain of Collabora, where you can find the frontend. Defaults to "collabora.owncloud.test"
      COLLABORA_DOMAIN=
      # Admin user for Collabora. Defaults to blank, provide one to enable access
      COLLABORA_ADMIN_USER=
      # Admin password for COllabora. Defaults to blank, provide one to enable access
      COLLABORA_ADMIN_PASSWORD=
    
    

    You are installing oCIS on a server and Traefik will obtain valid certificates for you so please remove INSECURE=true or set it to false.

    If you want to use the Traefik dashboard, set TRAEFIK_DASHBOARD to true (default is false and therefore not active). If you activate it, you must set a domain for the Traefik dashboard in TRAEFIK_DOMAIN= eg. TRAEFIK_DOMAIN=traefik.owncloud.test.

    The Traefik dashboard is secured by basic auth. Default credentials are the user admin with the password admin. To set your own credentials, generate a htpasswd (eg. by using an online tool or a cli tool).

    Traefik will issue certificates with LetsEncrypt and therefore you must set an email address in TRAEFIK_ACME_MAIL=.

    By default oCIS will be started in the latest version. If you want to start a specific version of oCIS set the version to OCIS_DOCKER_TAG=. Available versions can be found on Docker Hub.

    Set your domain for the oCIS frontend in OCIS_DOMAIN=, eg. OCIS_DOMAIN=ocis.owncloud.test.

    If you want to change the OIDC client id of th ownCloud Web frontend, you can do this by setting the name to OCIS_OIDC_CLIENT_ID=.

    You also must override three default secrets in IDP_LDAP_BIND_PASSWORD, STORAGE_LDAP_BIND_PASSWORD and OCIS_JWT_SECRET in order to secure your oCIS instance. Choose some random strings eg. from the output of openssl rand -base64 32. For more information see secure an oCIS instance.

    By default the oCIS WOPI server extension will be started in the latest version. If you want to start a specific version of oCIS WOPI server set the version to OCIS_WOPISERVER_DOCKER_TAG=. Available versions can be found on Docker Hub.

    By default the CS3Org WOPI server will also be started in the latest version. If you want to start a specific version of it, you can set the version to CS3ORG_WOPISERVER_DOCKER_TAG=. Available versions can be found on Docker Hub.

    Set your domain for the CS3Org WOPI server in WOPISERVER_DOMAIN=, where Collabora can download the files.

    You also must override the default WOPI JWT secret, in order to have a secure setup. Do this by setting WOPI_JWT_SECRET to a long and random string.

    Now it’s time to set up Collabora and you need to configure the Domain of Collabora in COLLABORA_DOMAIN=.

    If you want to use the Collabora admin panel you need to set user name and passwort for in COLLABORA_ADMIN_USER= and COLLABORA_ADMIN_PASSWORD=.

    Now you have configured everything and can save the file.

  • Start the docker stack

    docker-compose up -d

  • You now can visit oCIS and are able to open an office document in your browser.

Local setup

For a more simple local ocis setup see Getting started

This docker stack can also be run locally. One downside is that Traefik can not obtain valid SSL certificates and therefore will create self signed ones. This means that your browser will show scary warnings. Another downside is that you can not point DNS entries to your localhost. So you have to add static host entries to your computer.

On Linux and macOS you can add them to your /etc/hosts files like this:

127.0.0.1 ocis.owncloud.test
127.0.0.1 traefik.owncloud.test
127.0.0.1 collabora.owncloud.test
127.0.0.1 wopiserver.owncloud.test

After that you’re ready to start the application stack:

docker-compose up -d

Open https://collabora.owncloud.test and https://wopiserver.owncloud.test in your browser and accept the invalid certificate warning.

Open https://ocis.owncloud.test in your browser and accept the invalid certificate warning. You are now able to open an office document in your browser.
